"In the middle of all the tension and destruction, there is a laughter of absolute sanity that might sound like someone insane. Maybe laughter is the voice of sense. I always tell my students that you cannot take everything too seriously because at will kill you. If you carry bitterness and hatred around, it gives you arthritis, rheumatism, cancer. Certainly, I have to be aware of everything that is happening, but I can't let it kill me. (1994)"
